Therefore, the limiting block can not prevent the upper die from being inserted into the first through hole, but the upper die can be prevented from passing through the first through hole, and risks are caused to a base or an operator of the press machine.
In some embodiments, the moving mechanism includes a guide rod and a slide block, which are matched with each other, the guide rod is disposed along the extending direction of the first through hole, the top end of the guide rod is connected with the upper die, and the guide seat or the lower die is connected with the slide block. Therefore, when the upper die is pressed, the guide rod can drive the upper die to move relative to the sliding block.
In some embodiments, the cutting edge of the first tool bit is arranged in a concave structure, and the center of the concave structure is arranged towards the lower die.
The cutting edge of the first cutter head is not simultaneously contacted with the surface of the product to be punched, namely, the contact surface of the cutting edge of the first cutter head and the surface of the product to be punched is reduced, the punching pressure is improved, and the punching quality of the product is improved.
In some embodiments, a base is arranged below the lower die, and a second through groove communicated with the first through hole is defined between the base and the bottom surface of the lower die. The base of the press machine is prevented from being damaged when the upper die penetrates through the first through hole, and the problem that the first cutting edge of the upper die is abraded due to the fact that the upper die penetrates through the first through hole is avoided.
